1) Aim To observe the magnetic field produced by a current carrying loop.
2) Run the simulation and observe the conductor and the field lines.
3) Notice the change in the field lines as the conductor forms a loop.
4) Finallly, the direction of the magnetic field due to each loop is in same direction.

Note: You can also observe how the intensity of the magnetic field varies while the loop is being formed, by checking the "show flux" checkbox.
Observe: What happens when the direction of the current is changed ? Does it have any effect on the field lines?
